Tallysman Wireless has added the SSL889XF dual-band GNSS antenna to its line of GNSS products.
The SSL889XF employs Tallysman’s Accutenna technology providing GPS, QZSS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, and BeiDou B1/B2b coverage. The SSL889XF antenna is designed for precision dual-frequency positioning where a light weight and a low profile are important.
The SSL889XF antenna element is 48 mm in diameter and 20 mm tall and weighs ~50 g. It has a tight average phase center variation of less than 10 mm for all frequencies and overall azimuths and elevation angles.
The SSL889XF is available in three versions. Model SSL889XF-1 has an integrated 61 mm ground plane and two mounting holes. Model SSL889XF-2 has a mounting collar, and model SSL889XF-3 is the antenna only and is attached using adhesive tape.
All models have a female MCX connector.
The SSL889XF antenna also supports Tallysman’s eXtended Filtering (XF) technology.
Tallysman Wireless has added the housed AJ977XF triple-band antenna with anti-jam technology to its line of GNSS products.
According to Tallysman, the AJ977XF uses a novel stacked antenna phased array that creates a null of typically 20-dB attenuation in the antenna’s radiation pattern from the horizon to an elevation angle of approximately 15 degrees.
The null in the radiation pattern strongly mitigates in-band and out-of-band signals. For example, the AJ977XF will continue to function in the presence of a ground-level 600-watt jamming signal, 100 meters or greater from the antenna. In addition to the null in the radiation pattern, the antenna’s OP1dB (compression point) is 15 dBm, which strongly protects the antenna’s low-noise amplifier (LNA) from saturating.
The triple-band AJ977XF antenna supports GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5ab and BeiDou B1/B2ab), and, in the region of operation, satellite-based augmentation systems (SBAS): WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India).
The AJ977XF is housed in a through-hole mount, weatherproof (IP67) enclosure. L-bracket (PN 23-0040-0) or pipe (23-0065-0) mounts are available for permanent installations.
The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated. Their signals or their harmonics can affect the proper operation of GNSS antennas and receivers.
In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can negatively affect the reception of GNSS signals. Similarly, new LTE signals in Europe [band 32 (1452–1496 MHz)] and Japan [bands 11 and 21 (1476–1511 MHz)] also have been shown to affect GNSS signal reception. Tallyman’s new AJ977XF mitigates the effects of these new signals.
Tallysman Wireless has added the housed SSL990XF full-band survey-grade GNSS antenna to its line of GNSS products.
The SSL990XF uses a derivative of Tallysman’s patented VeroStar antenna element to provide full GNSS + L-band corrections frequency coverage.
The SSL990XF is 63 mm in diameter and 28 mm tall and weighs ~50 grams, making it a very small and light housed full-band precision antenna. It has a very tight average phase-center variation of 4 mm or lower for all frequencies and overall azimuths and elevation angles.
The full-band SSL990XF antenna supports GPS/QZSS L1/L2/L5, QZSS L6, GLONASS G1/G2/G3, Galileo E1/E5ab/E6 and BeiDou B1/B2ab/B3, as well as L-band correction services. Also supported in the region of operation are satellite-based augmentation systems: WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India).
The SSL990XF is housed in a weatherproof (IP67) enclosure and is mounted using either adhesive tape or a mounting collar that includes a waterproofing O-ring. Two antenna cable connector options are available. The first is a female SMA, and the second is an MCX. It is an ideal antenna for precision UAV and all applications where light weight and precision matter.

Tallysman has designed the XF feature to mitigate interference from all near-band signals and ensure that the antenna provides the purest GNSS signals.
The radio-frequency spectrum has become congested worldwide as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526–1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539–1559 MHz). New LTE signals in Europe (band 32, 1452–1496 MHz) and Japan (bands 11 and 21, 1476–1511 MHz) have also affected GNSS signals.
Tallysman’s housed helical antennas weigh ~42 g and are enclosed in a robust military-grade IP67 plastic enclosure. The antenna base has an integrated SMA connector, a waterproofing O-ring, and three screw holes to enable secure attachment. Tallysman’s embedded helical antennas weigh ~8 g and are easily mounted with an optional embedded helical mounting ring, which traps the outer edge of the antenna circuit board to the host circuit board or any flat surface.
An MCX connector is installed in the base of the antenna.
Tallysman helical antennas are suitable for a variety of applications, including lightweight unmanned autonomous vehicle navigation (land, sea and air), land survey devices, automotive positioning, timing and other precise-positioning applications.

Tallysman Wireless has added the housed HC885XF and embedded HC885EXF dual-band eXtended Filtering (XF) antennas to its line of helical antennas.
The antennas receive GPS/QZSS L1/L5, GLONASS G1/G3, Galileo E1/ E5a/b, BeiDou B1/B2/B2a and L-band corrections services.
Historically, dual-frequency antennas and receivers commonly supported GPS L1 and L2 and GLONASS G1 and G2. In recent years, GPS, GLONASS, Galileo, BeiDou and NavIC have added GNSS signals in the L5 frequency band (1160-1217 MHz).
As a result, the new dual-frequency GNSS standard has become L1 and L5.
Tallysman’s new HC885XF antenna has been tuned to provide optimal support for the entire L1/G1/E1/B1/L-band correction and L5/G3/E5/B2 bands.
The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539-1559 MHz). New LTE signals in Europe [Band 32 (1452-1496 MHz)] and Japan [Bands 11 and 21 (1476-1511 MHz)] have also affected GNSS signals. Tallyman’s XF models mitigate the effects of these new signals.

XF Coming to All Lines
eXtended Filtering enables the HC997EXF antenna to mitigate new and existing radio frequency bands that interfere with GNSS signals. The custom XF filtering has been tested to mitigate new (Europe and Japan) and existing LTE signals, enabling the XF antennas to produce clean and pure GNSS radio frequency data.
For example, in North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, could affect GNSS antennas that receive space-based L-band correction service signals (1539–1559 MHz).
Similarly, LTE signals or their harmonics, such as the new LTE bands in Europe–Band 32 (1452–1496 MHz)–and Japan–Bands 11 and 21 (1476–1511 MHz)–have affected GNSS antennas and receivers.
Lastly, the Inmarsat satellite communication uplink (1626.5–1660.5 MHz), commonly used on maritime vessels, can also affect nearby GNSS antennas.
Tallysman Wireless also has added eXtended Filtering (XF) to its TW3800 series of Accutenna precision antennas, and will be rolled out to all of Tallysman’s product lines.
Tallysman Wireless Inc. has added the TW7976 to its surface mount line of antennas. The TW7976 covers GPS/QZSS-L1/L2, QZSS-L6, GLONASS-G1/G2, Galileo-E1/E6, and BeiDou-B1/B3, as well as L-band correction signals.
The addition of L6 and E6 coverage supports the Galileo High Accuracy Service (HAS) and the QZSS Centimeter Level Augmentation Service (CLAS) correction signals. Regional augmentation services such as WAAS (North America), EGNOS (Europe), MSAS (Japan), GAGAN (India) and high-precision L-band correction services are also supported.
The TW7976 features a patented Tallysman Accutenna, which provides multi-constellation and multi-frequency support. Accutenna technology offers an excellent axial ratio that mitigates multipath signals and produces clean code and phase measurements. Accutenna antennas enable high-precision techniques, such as real-time kinematic (RTK) and precise point positioning (PPP), which provide accurate and precise position estimates (< 0.1 m).
Another key feature of the TW7976 is a deep pre-filter that attenuates out-of-band signals. This is crucial in challenging urban environments where near-band and inter-modulated signal interference from LTE and other cellular bands is common.
The surface-mounted TW7976 weighs 180 grams, is IP67-rated, and supports direct screw, magnet or adhesive-tape attachment. The TW7976 is ideal for many applications, including autonomous vehicle navigation (land, rail, sea, and air) and high-precision automotive and agricultural positioning.
Tallysman Wireless Inc. has added the TW162A automotive-grade smart power GNSS signal splitter to its line of GNSS accessories.
The Tallysman TW162A signal splitter supports the full GNSS spectrum: GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3, and L-band correction service frequency band.
Vehicle rooftop antenna space is often at a premium, and mission applications often require more than one GNSS receiver. The TW162A supports this use case where one GNSS antenna provides the signal to two GNSS receivers.
It also offers key fail-over and fault-identification features.
First, the splitter accepts power from all attached GNSS receivers; if one receiver fails, the next attached receiver automatically provides power to the splitter and antenna.
Second, if the antenna fails and does not draw current, all connected receivers will sense a current draw lower than 1 mA, indicating an antenna fault.
The TW162A offers high performance in terms of noise figure, isolation and linearity. TW162A is built with Automotive Electronics Council AEC-Q100 certified components, ensuring a wide operational temperature range and a long service life. It has been rigorously tested and is packaged in a durable, compact and lightweight aluminum housing.
The TW162A is available with three Z or A+B+C FAKRA connectors.
Tallysman Wireless has added new eXtended Filtering (XF) features to the TW3900 series of Accuntena precision antennas. Tallysman designed the XF feature to mitigate interference from all near-band signals and ensure that the antenna provides the purest GNSS signals.
Tallysman’s TW3972XF, TW3972EXF, TW3972LGXF, TW3967XF, and TW3967LGXF are triple-band antennas that support GPS/QZSS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5ab), BeiDou (B1/B2/B2a), NavIC L5, and L-Band correction services.
Worldwide, the radio frequency spectrum has become congested as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539–1559 MHz).
